r device of this character embodying a novel. construction and arrangement of parts whereby a combined safety razor and strepping mechanism is provided, the device being readily convertible from a safety razor to a blade sharpening device.

Other objects of the invention are to provide a combined safety razor and stropper which will be simple in construction, strong, durable, efficient in use and which may be manufactured at low cost. I

All of the foregoing and still further objects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein: I

Figure 1 is a view in vertical longitudinal 0,, section through a combined safety razor and stropper constructed in accordance with this invention.

Figure 2 is a top plan view of the device,

Figure 3 is a horizontal sectional view taken substantially on the line 33 of Figure 1 looking in the direction indicated by the arrows,

Figure l is a vertical cross sectional view taken substantially on the line l4l of Figure 2 showing the device ready for use as a safety razor.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a substantially rectangular, flat metallic plate having integral, upturned side flanges 2 provided with the horizontally and upwardly inclined extensions 8 on their ends which project beyond the front and rear edges of the plate 1. A substantia ly U- shaped bracket 1 is mounted transversely on the plate 1 and said bracket and the plate 1 are provided with centrally disposed registering openings for the passage of a screw 5 for rigidly securing the plate 1 and the bracket 4 on the upper end of a handle 6.

The bracket 4 fits snugly between the side '5, 1939. Serial No. 482,511.

flanges 2 of the plate 1. Journalled in the upper end portions of the upstanding arms of the bracket 4: is a shaft 7 having fixed on one end portion a gear 8. Fixed on the shaft 7 between the upstanding arms of the bracket -l is a permanently mounted blade engaging jaw 9 having the offset blade gripping marginal portion 10 on one side of the shaft 7 and having the slightly arcuate flanges 11 formed integrally thereon on the 59 other side of the shaft 7.

A movable jaw 12 is disposed in opposed relation to the jaw 9 on the opposite side of the shaft '2' and the aws 9 and 12 are positively clamped together by the bolts 13. On one side of the shaft 7 the movable jaw 12 is provided with an offset blade gripping portion 1st and on the othe side of the shaft 7 the jaw 12 isprovidcd with the slightly arcuate flanges 1.5 which are disposed in abut m ting engagement with the flanges 11 of the jaw 9. As will be seen from 2, the flanges 11 and 15 are formed on pairs of rearwardly projecting portions of the two jaws.

A. retaining spring or resilient finger 16 is engageable with the jaw 1 and is secured in position through the medium of the integral cross bar 17 connected to the rear end thereof with its ends fitting between the flanged parts of the two jaws. This cross bar 17 is of considerable width and acts to space the rear parts of the jaws apart and the finger 16 in lowered position so that the front parts 10 and 14- will. clamp a blade 8 F I Hr 8 placed between them, as shown 11] rd 1g. 4-. By raising the finger 16, the bar 17 is turned so that the rear part of the jaws are free to move towards each other so that the front part will release pressure on the blade.

A longitudinally extending guide 19 is mounted centrally on the lJ-snaped bracket st for slidably receiving the metallic bar 20 having formed integrally on one end thereof a guard 21. Inte ral blade engaging and retaining lugs 22 are formed on the opposite ends of the guard 21 for engagement with the ends of the edge of the blade 18 for releasably retaining the cutting of said blade which is in use in engagement with and 1 in proper position on the guard 21.

At its other end the bar 20 has formed integrally thereon the upstanding abutment 23 to which is secured in any suitable manner, such as by soldering or welding one end portion of a substantially U-shaped spring 24 the opposite end portion of which is engaged with the adjacent end of the guide 19 in a manner to yieldingly urge the abutment 23 away from the guide 19 and engage the retaining lugs 22 operatively with the blade 18.

It may be well to here state that when the blade 18 is engaged with the guard 21 in the manner illustrated in Figure 4 of the drawings, the device is ready for use as a safety razor. A coiled spring 25 encircle the shaft 7 adjacent one of the upstanding arms of the U-shaped bracket 4 and has one end anchored to said one arm and its other end secured in any suitable manner as by soldering, to the movable jaw 12 in a manner to normally and yieldingly urge the jaws 9 and 12 and the blade 18 into raised position away from the guard 21 when rollers have ceased to function.

Driving rolls 26 are fixed on the shafts 27 which are journalled in intermediate portions of the extensions 3 of the upturned side flanges and fixed on one end of each of the shafts 27 is a gear 28. The gears 28 are operatively connected with the blade reversing gear 8 through the medium of the intermediate gears 29 which are rotatably supported on one of the side flanges 2.

As will be apparent, each of the gears 29 is in mesh with the blade reversing gear 8 and with the adjacent driving gear 28. Pressure rolls 30 are fixed on the shafts 31 which, in turn, are journalled between the upwardly direct-ed end portions of the extensions 3 and the rolls 30 are thus disposed above the horizontal plane of the rolls 26 and are spaced therefrom.

A strop 32 is trained under the pressure rolls 30 and over the driving rolls 26 in the manner clearly illustrated in Figure 1 of the drawings. When it is desired to strop the blade which is being used in the razor the device is reciprocated on the strop 32 and 'at the beginning of each stroke the blade 18 will be reversed through the medium of the gears 28, 29 and 8 as will be apparent.

Vhen used as a stropping device, the invention is assembled as seen in Figures 1 and 2 of the drawings and in this position the guard 21 is retracted by a spring 24 to a position above the plate 1. When the device is to be used as a safety razor, the bracket 4 is mounted directly on the handle 6 in the manner clearly seen in Figure 4 of the drawings and the guard 21 is projected away from the bracket 4 against the tension of the spring 24 to engage the retaining lugs 22 with the blade 18.

As beforeexplained, the spring 25 also assists in retaining the blade 18 engaged on the guard 21 and it also acts to raise the blade from the guard, when the blade is released from the section 22 and to normally hold the parts with the blade in vertical position. It is believed that the many advantages of a combined safety razor and stropper constructed in accordance with this invention will be readily understood, and a though the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction may be had which will fall within the scope of the invention as claimed.

laying thus described my invention, what I claim as new is:

A blade holder of the class described comprising a bracket, a shaft having its end journalled in the bracket, a lower jaw plate having the rear part of the upper face connected with the shaft, an upper jaw plate, means for connecting intermediate portions of the jaw plates together, each jaw plate having a pair of spaced rearwardly extending portions extending beyond the shaft and having arcuate flanges at the rear ends, the flanges of the lower jaw plate extending upwardly and those of the upper jaw plate extending downwardly and overlapping the flanges of the lower j aw plate, a bar of considerable width passing between the two sets of rearwardly extending portions, a spring finger connected with the bar at the central part of its upper edge and said finger being curved adjacent its point of connection with the bar, said. curved portion passing between the rearwa-rdly extending portions of the upper jaw plate, said finger resting upon the upper jaw plate and applying pressure thereto when the bar has been turned on edge to move the rearwardly extending portions of the two jaw plates away from each other, to cause the opposite ends of the jaw plates to clamp a blade between them.

In testimony whereof I affix my signature.
